G390167000 25.4 mm UVFS Optical Flat Window; t=5mm Uncoated

The G390167000 is a 25.4 mm UVFS Optical Flat Window with a thickness of 5mm, sourced from Qioptiq Photonics. This window is designed to be uncoated, providing a clear, unaltered view of the optical path.

The window is of the Flat Window subtype, which means it is designed to maintain the direction of light propagation without deviation, reflection, or dispersion. This makes it ideal for applications where minimal optical interference is required.

The window is circular in base shape, with a diameter of 25.4 mm. This shape is common in optical systems due to its symmetry and ease of alignment. The window's thickness of 5mm provides structural rigidity while minimizing optical distortion.

The window is made of UVFS, a type of fused silica. This material is known for its high transparency across a wide range of wavelengths, including the ultraviolet spectrum. It also has a low coefficient of thermal expansion, making it resistant to thermal shock.

The window is designed for use at a wavelength of 633 nm. This wavelength falls within the visible light spectrum, making the window suitable for applications involving visible light.

The window is shaped as a Thin Lens, which means it has been precisely ground and polished to a specific curvature. This shape can be used to focus or collimate light, making it useful in a variety of optical systems.

The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in applications where coatings may introduce unwanted optical effects or where simplicity and cost-effectiveness are paramount.
